Abstract
a presente invenção se refere ao fornecimento de uma chapa de aço galvanizada imersa a quente que inibe, de maneira única, a geração excessiva de óxido de zinco em uma camada de superfície após a prensagem a quente e que tem resistência à corrosão superior em uma porção não pintada. uma chapa de aço galvanizada imersa a quente de acordo com a presente invenção compreende uma chapa-base de aço que é um substrato, uma camada galvanizada imersa a quente fornecida na chapa-base de aço, e uma camada tratada de superfície formada na camada galvanizada imersa a quente em pelo menos um lado, em que a camada tratada de superfície contém 0,1 a 12 g/m2 que inclui por lado, em termos de metal, um óxido granular cuja energia livre padrão de formação (¿g0) é inferior à energia livre padrão de formação de óxido de zinco (¿g0zn) e maior que a energia livre padrão de óxido de alumínio (¿g0al) na mesma temperatura na faixa de temperatura de 482,22 a 704,44 oc (900 a 1.300 k), e em que o diâmetro de partícula do óxido granular inclui 3 a 100 nm.the present invention relates to the supply of a hot-dip galvanized steel sheet which uniquely inhibits the excessive generation of zinc oxide in a surface layer after hot pressing and which has superior corrosion resistance in one portion not painted. a hot-dip galvanized steel sheet in accordance with the present invention comprises a steel base sheet which is a substrate, a hot-dip galvanized sheet supplied in the steel base sheet, and a surface treated layer formed in the galvanized layer hot-dipped on at least one side, where the surface-treated layer contains 0.1 to 12 g / m2 which includes, in terms of metal, a granular oxide whose standard free energy of formation (¿g0) is lower to the standard free energy of zinc oxide formation (¿g0zn) and greater than the standard free energy of aluminum oxide (¿g0al) at the same temperature in the temperature range of 482.22 to 704.44 oc (900 to 1,300 k ), and where the particle diameter of the granular oxide includes 3 to 100 nm.
